Podium
Podium
A podium turns a Vellum diagram into a presentation. Each slide is a framed region of the canvas; presenting pans and zooms between them.
The diagram stays the source. There is no export step, so the deck cannot drift from the drawing.
Slides and chapters
A slide is a view of the diagram rather than a copy. Editing the diagram changes what the slide shows.
A chapter is a diagram tab. Slides belong to a chapter, and the audience walks one flat sequence across every chapter in order: chapter one's slides, then chapter two's, and so on. Reordering within a chapter reorders the talk; reordering the tabs reorders the chapters.
The transition follows that structure:
| Moving | Looks like |
|---|---|
| Between slides in one chapter | A pan and zoom across the same canvas |
| Across a chapter boundary | A morph to the next diagram |
Put a change of subject in a new chapter, and keep one argument's slides in one tab.
Presenting
Present mode fills the screen. The keys:
| Key | Does |
|---|---|
| → / Space | Next slide |
| ← | Previous slide |
| PageDown / PageUp | Next / previous |
| Home / End | First / last slide |
The pill shows the current slide's name, falling back to "Slide n" when you have not named it. The chapter name is in the pill's tooltip rather than on the pill itself.
The laser pointer (L in the editor) works here too.
Strata as speaker material
A slide can show the strata attached to shapes in view, as cards beside the diagram.
Sharing
A podium is part of its blueprint and inherits its visibility. Anyone who can read the blueprint can step through the podium.
The Podium Recorder extension, which captures a flow in the browser and turns it into a deck, is on the roadmap and not yet installable. Build podiums from the diagram for now.
